According to the integral oil tank and the manufacturing method thereof, the integral oil tank comprises a framework and a skin, the framework is of a main force transmission structure, the skin is made of a whole composite material, the skin and the framework are integrally formed and designed, the skin wraps the framework, the skin and the framework are co-glued and cured, and the position of a fuel oil filling port cover is arranged on the skin. The problems that in the prior art, the number of oil tank connecting standard parts is large, the number of formed holes is large, the number of skin butt joints is large, the sealing difficulty is large, and the formed oil tank has the high oil leakage risk in the using process are solved.
Description
technical field [0001] The invention belongs to the technical field of fuel tank design, and in particular relates to an integrally formed fuel tank. Background technique [0002] In modern aircraft structural design, rubber soft fuel tanks and integral fuel tanks are mostly used in fuel tanks, and the integral fuel tanks are further divided into conventional fuel tanks sealed with welded seals and sealants. The manufacturing process of the rubber soft fuel tank is cumbersome and complicated, the cost is high, and the volume utilization rate of the structural space is not high. Most of the welded fuel tanks are metal welded structures such as aluminum alloy or stainless steel, and the weight ratio is high. Therefore, more and more fuel tank structures adopt conventional integral fuel tanks sealed with sealant. The sealant seal overall fuel tank generally adopts a skeleton skin structure, and the skin is formed by composite materials, which effectively reduces the structural...
